120 Stitches

The stitch patterns are put into 3 groups with mode 1 having the 10 basic stitches, and mode 2 for the utility stitches, while mode 3 is for the decorative stitches.

It also has Gothic style letters and numbers located in modes 4 to 6

There is a detachable reference chart for the stitches, and this chart can be displayed on top of the sewing machine on a pin that’s inserted into a hole designed for it, and the chart can be folded down on the back when not needed.

On the LCD screen you can select your stitches by pushing the mode key and it shows the recommended stitch length and width, as well as the foot to use with that stitch.

The stitch width and length can also be fine-tuned to your preference with the stitch width key.

Also in mode 2 you can choose the buttonhole pattern you wish to use.

Top Loading Bobbin

The bobbin on the 4120QDC is by the easy top-loading system, and is jam proof.

You can remove the hook cover for the bobbin by just pushing a button on the plate, then your bobbin just drops into place with the thread unwinding counter clockwise, then pull the thread into the notch on the front, then to the left until thread goes into the notch on the side, then extend about 6 inches of thread to the back, install cover.

The cover also has a diagram of how thread from the bobbin goes and is see through, so you know when thread is getting low.

The bobbin and thread windings are clearly marked on the top of the machine for convenience.

Thread Cutter

An excellent feature on this machine is the thread cutter button, which when pressed can cut both the top and bottom threads.

The machine will sew up to 820 stitches per minute, and has a speed control slider on the front to control the speed.

Also, on the foot control just press down to start the machine sewing and the harder you press the faster it will sew.

There is a start/stop button on the front, but it cannot be used if the foot control is attached.

Snap-On Presser Feet

Thread Tension

There is a tension control dial located on the front, that can be adjusted.

Setting number 4 is for general sewing, while higher numbered settings or for increased tension.

Foot Pressure Dial

For adjusting the foot pressure, there is a dial at the top back of the machine with 6 being used for heavier fabrics, and lower numbers for finer fabrics, and is very handy when doing quilts.

  1. I haven’t done a lot of sewing in my time, but this machine is impressive. The buttons can seem a little overwhelming, but the functions this thing can perform are amazing. 

    I will be looking at this when I am ready to purchase a sewing machine, which may be sooner now that I have read your post. Thank you.

    Would this machine be good for commercial use? We are thinking about getting into the house flipping market and I can make certain things to go with each house we turn.

    • Hi Tina

      The Janome 4120QDC is beginner’s friendly, so don’t be afraid to try it, it’s easy to set up and start sewing with it.

      This model is good to do some home decor projects, but if you want to start making big projects often as part of your business as house flipping agent, I will suggest to take a look to a bigger model like theJuki TL-2010Q 

  2. When it come to sewing or quilting, the Janome 4120QDC seems to be the machine everyone is confident about. My aunt whom I stayed with for 7 years is a fashion designer and she wouldn’t stop raving about the machine so I had to come check out what the hype was all about. 

    I have to say though, this is such a detailed review, it provides so much clarity into the reason why so many people thinks its the ideal sewing machine. The 820 stitches per minute maximum speed is so impressive. Imagine how much work can be done in a relatively small amount of time. This is really informative.

    Thanks for sharing

  3. I used my old sewing machine for over 30 years but found it was not as easy to use as the
    new models. The stitching didn’t look even and it was limited in features.

    Being able to select different stitches and having a built-in needle threader make
    upgrading to a newer model worth the expense.

    I enjoyed watching the video to learn about the features. Since I am looking for
    something that will last another 30 years the warranty is perfect.

    • Hi Sharon,

      I also used to sew with an old sewing machine, 10 years ago I got a new one and it made a big difference, a month ago, I just bought a new model, and I can tell you, there’s a big difference how well new sewing machine can work!

  4. Wow the standard features on the Janome 4120QDC are pretty outstanding. Features such as 120 built-in utility and decorative stitches, 15 needle positions, 820 stitches per minute maximum speed and LCD control screen really jumped out at me especially. I’m glad to see that there are Gothic style letters options. Also, that the top-loading system is jam-proof is always helpful. I think this will make for the perfect gift, and I have saved your post to do just that. Great recommendation and keep up the good work!

    • Hi Pentrental

      This sewing machine has everything any sewer or quilter will love to have in a unit to work on many projects!

      Thanks for read my blog today!

  5. Hello Alex, thank you for sharing your review of Janome 4120QDC Sewing Machine. I can’t believe the level and height at which sewing machine technology has gone. I am pretty blown away by this particular model. I love the features and the guide that comes with it too. This sewing machine is indeed a game changer and I really wished to get something like this for my friend. It surprises me to know that there aren’t any reasonable cons as far as this sewing machine is concerned. Nice.


    • Hi Mr Biizy

      Yes, sewing machines have come a long way from the days of the first sewing machine, today’s model are light and rich features, your friend will be so happy if you get one of this model for your friend. 

  6. Wow. I’m really amazed by its features especially the warranty period. This shows how quality this product is. Apart from its features, the two things that I found awesome here is that it’s light weight and can be carried around. My younger sister is having a sewing class and I think that she will find this machine very to be very interesting.
